My website has two different domains. Some pages are in domain 1 and some are in domain2. I have a requirement where I have to read data from a first party cookie in domain 2 and use that data when user go to domian 1 from domain 2. Both domain uses same DTM web property.
I tried session level data element and DTM local storage but no luck. Value of data element / local storage set in domain 2 are not available in domain1.
Is there any solution by which this can be achieved ?. Will "span across multiple domain" in web property setting help ?
We (Search Discovery Inc) have developed a technology called Storage Spanner that allows you to securely use localStorage across domains. The solution works in DTM but does not require DTM. I will soon be building a Launch extension to make it super easy to implement in that environment.
One thought - I forgot to ask. Are both domains on the same top level domain? (i.e. www1.foo.com & www2.foo.com are both on the top level domain "foo.com") . If this is the case you can use a cookie set on the TLD which would span both.
If not, there really is no solution within DTM or Launch to do this.
